The study aimed to develop a novel gel loaded with nanosponges containing fucoidan extracted from Dictyota bartayresiana for arthritis treatment. Brown algae are rich in fucan, a group of sulfated polysaccharides with superior healing properties. Among the numerous fucoidan sources, a species, Dictyota bartayresiana, was selected from the family Dictyotaceae for arthritis screening. Many types of arthritis are characterized by inflammation, stiffness, redness, and pain. The protein denaturation method was used for the in vitro anti-arthritic study of ethanolic extract of Dictyota bartayresiana. Percentage inhibition of five series of concentrations ranging from 100 – 1000 µg/ml of test solution showed values of 51.86% w/w, 55.56% w/w, 59.26% w/w, 65.19% w/w, and 85.49% w/w concerning with the standard, respectively. A concentration of 1000 g/ml induced an effective percentage inhibition. Fucoidan’s beneficial properties guide the development of effective formulations. Fucoidan isolated from algae is formulated in the form of nanosponges using an emulsion solvent diffusion method and developed in gel-loaded nanosponges with the help of carbopol 940 polymer. Because of the nanosize...

This work aims to evaluate the antimicrobial potential of ethanol, methanol, and water extracts of cherry (Prunus avium) and acetone extracts of quince (Cydonia oblonga), hexane & ethyl acetate extracts of Handh (Taraxacum officinale), acetone & methanol extracts of sustchal (Malva neglecta) of the selected minor fruits and vegetables of Indian Himalayan Region. Agar well diffusion method has been used to determine the antimicrobial activities and minimum inhibitory concentrations (MIC) of different plant extracts against Gram-positive (Staphylococcus aureus), Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa) and two strains of fungus (A. niger, A. flavus). The extracts exhibited both antibacterial and antifungal activities against tested microorganisms. The concentration increase of the extracts resulted in the increase of inhibition zone values resulting in the increase in the antimicrobial activities of the extracts. Both pulp and peel of Quince (Cydonia oblonga) exhibited significant antimicrobial activity. Acetone Quince (Cydonia oblonga) and Handh (Taraxacum officinale) extract showed significant antibacterial activity (P < 0.05) against all tested bacterial...

Diabetes mellitus is a metabolic disorder caused due to lack of insulin and/or its insufficiency. It is ranked ninth among the leading causes of death globally. As Oral hypoglycemic agent usage causes one or more side effects, phytochemicals can be used as alternative herbal medicine to treat diabetes mellitus with little or no side effects. In the current study, Cuminic acid was evaluated for its antioxidant and antidiabetic activities under in-vitro. Different doses of Cuminic acid were used to analyze free radical scavenging effect by DPPH, H2O2 & NO methods. α- amylase and α- glucosidase inhibitory effects were studied using various doses of Cuminic acid. Glucose diffusion inhibitory assay was carried out using a Dialysis bag. In the results of the antioxidant study, Cuminic acid showed the highest free radical scavenging activity in all the methods compared to standard Ascorbic acid. Enzyme inhibition studies also showed significant increase in antidiabetic activity indirectly with increasing concentrations of Cuminic acid, which was found to be equivalent to the standard drug acarbose....

Febuxostat (FXT), used for treating gout, is poorly soluble and is susceptible to enzymatic degradation when administered as tablets. The current study aims to formulate, optimize and develop a stable Liquid self-nanoemulsifying drug delivery system (L-SNEDDS) and Solid SNEDDS to improve solubility, resulting in enhanced bioavailability and further to formulate Self-Nano emulsifying Osmotic Pump Tablets (SNEOPT) for controlled drug release. A ternary plot was constructed with Capmul MCM (oil phase), Tween 80 (surfactant), and PEG 400 (co-surfactant). Further optimization was done by D-Optimal design. Optimized L-SNEDDS (F8) was then converted to S-SNEDDS by the adsorption method. Aerosil 200 was used as an adsorbent. The L-SNEDDS and S-SNEDDS were characterized and evaluated. The particle size of the optimized batch was 97.25 nm (L-SNEDDS) and 155.2 nm (S-SNEDDS). In-vitro dissolution studies showed>75% release in pH 1.2 HCl buffer and >80% in phosphate buffer pH 7.4 in 1 hour. SEM (Scanning electron microscopy) studies indicated spherical particle morphology. SNEOPT was prepared by direct compression (with NaCl as the osmogent). In-vitro release from...

Computational chemistry is a robust and economical tool for designing and developing potent therapeutic molecules. Benzimidazole and its analogues are compounds with a unique pharmacophore that derives its application as broad-spectrum antimicrobial agents. A quantitative structure-activity relationship (QSAR) study was performed using a data set of 28 benzimidazole analogues with antimicrobial activity. Descriptors were generated using various free software’s such as PaDEL-Descriptor, SwissADME and OCHEM (Online chemical modelling environment). The statistical analysis was performed using the Stats. Blue software by multiple linear regression (MLR) method for determining the relationship between dependant variable and various independent variables. The best QSAR model had an r2 value of 0.6773, and the predictive r2 value for external validation was 0.7150. The results show that a positive correlation is established between the descriptors, TPSA (Topological polar surface area), H-bond acceptors, iLOGP (Implicit LOGP), GGI4 (Galvez topological charge indices of order 4), thereby achieving the most accurate...
